About Me

Hi! I'm a Member of Technical Staff at a stealth startup. Previously, I was a research intern at UCSD Hao AI Lab, advised by Prof.Hao Zhang. I received my master degree in Robotics at UMich. Before that, I obtained my B.Eng. of Robotics with honors from Cho Kochen Honors College at Zhejiang University in 2023.

I'm deeply grateful for my time at Hao AI Lab—it was an incredibly formative journey working with such a passionate and inspiring team. If you're interested in MLsys and looking for research internships, don't hesitate to reach out to Prof. Hao Zhang!

I'm always happy to chat with people from diverse backgrounds—whether from academia or industry. Feel free to reach me at yongqichcd@gmail.com.
